Rollable Display Keyboard for Dynamic Typewriter-Style Typing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing portable electronic devices with rigid displays lack the ability to dynamically adjust presentation size and mimic the functionality of a typewriter, limiting their usability for text generation and manipulation.
Innovation Solution
An electronic system with an extendable display and input mechanism that monitors keystrokes to mimic a typewriter, automatically extending the display by increments corresponding to line spacing and font size, allowing for the insertion of new rows as needed.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a rigid display is used in portable electronic devices, then the device structure is simple and reliable, but the display cannot dynamically adjust presentation size to mimic typewriter functionality
Solution Approach 1:
The patent applies the dynamics principle by implementing a flexible display that can dynamically change its presentation size. The display transitions between a first presentation size for normal operation and a second presentation size that mimics a typewriter layout, allowing the display to adapt its physical characteristics based on the operational mode. This dynamic reconfiguration enables the device to provide different user experiences without requiring multiple separate devices.
2Productivity
If the display extends to provide more typing space, then text generation capability is improved, but the device occupies more space when not in use
Solution Approach 1:
The display is configured to dynamically extend when needed for text generation and retract when not in use. During typing operations, the display extends to provide additional virtual typing space, mimicking the behavior of a physical typewriter where the paper feed mechanism extends to accommodate longer text. When the display is not needed, it retracts to minimize the device volume, maintaining portability.
Solution Approach 2:
The flexible display is nested within the device housing when not in use, similar to how a telescoping mechanism works. The display can be rolled up or folded back into the device body, allowing the device to maintain a compact form factor when the extended display functionality is not required. This nesting approach enables the display to provide large typing space when needed while keeping the overall device volume small during storage or transport.

AI summary
An electronic device, method, and computer program product imitate a typewriter. A top horizontal row of a virtual typing sheet is presented on an upper portion of an extendable display. Keystrokes received by a text input device are monitored and corresponding characters are presented across the top horizontal row of virtual typing sheet. In response to a next line transitioning condition (e.g., reaching an end of a current row or detection of a return keystroke received via the text input device), the extendable display is triggered to upwardly extend by an increment corresponding to vertical dimensions of a line spacing and font size of the characters associated with the top horizontal row. Presentation of the virtual typing sheet and the top horizontal row at the corresponding line spacing are upwardly adjusted to insert a new lateral row for presenting keystrokes.
